Caution: The builT-in brake is noT a device for safely sTopping The machine. please insTall
anoTher safeTy sTopping device for The machine. when The builT-in brake is clamping The
moTor, roTaTion backlash can sTill occur and The maximum roTaTion is 1° – 2°. when a
moTor wiTh a brake is operaTing, The brake lining someTimes generaTes a noise (a swishing or
clicking sound). This is caused by The sTrucTure of brake module and is noT a malfuncTion.
iT will noT affecT The moTor’s funcTion.

If any odor, noise, smoke, vapor, or abnormal vibration occurs during motor operation, please
stop the motor and turn off the power immediately�

The values in the table above are maximum allowable values to be used with the listed drives.
The maximum values are well above the drive rated input current. Most applications can
use much lower fuse/breaker values. A smaller value of 125% - 175% of rated input current
is recommended. This allows for temporary motor overloads without tripping the circuit
protection.
The SureServo2 drives have an SCCR rating of 5kA. For short circuit protection, choose a
current-limiting fuse that limits the let-through current (at your installation's available fault
current level) to less than 5,000 Amps. For SureServo2, ADC recommends Class CC or JHL High
Speed Class J current-limiting fuses.
Example:
The time-current chart for JHL drive-rated fuses shows that a 30A JHL fuse will allow 50A for
an extended period of time before blowing.
A smaller fuse/breaker rating also helps with SCCR. The 30A JHL fuse above has a peak
let-through of less than 2,500A when connected to 100,000A RMS available fault current. A
60A JHL would allow a 5,000A peak with the same available RMS fault current. Using a smaller
fuse is better for device protection and SCCR ratings.
